mpls [ traffic-eng ] reoptimize timers frequency seconds
no mpls [ traffic-eng ] reoptimize timers frequency
Command introduced before JUNOSe Release
Specifies the frequency at which existing LSPS
are checked for better paths. RSVP-TE adds a random number in the
range 0–60 seconds to the specified value to prevent all LSPs
from being reoptimized simultaneously. The no version restores the default value, 3600 seconds.
Low timer values lead to frequent reoptimization of LSPs,
which is undesirable for the following reasons:
Frequent changes to the LSPs increases packet loss.
Frequent reoptimization increases the load on the router,
especially when the router acts as the LSP head end. The load is particularly
noticeable in a scaled network, resulting in high CPU utilization
on the router.
traffic-eng—Specifies optional keyword for compatibility
with non–E Series implementations
seconds—Number of seconds
in the range 0–604800; a value of zero means that no reoptimization
